Abstract
An image forming apparatus having an image bearing member on which an electrostatic image is formed, a first developer carrying member carrying a developer thereon, and a second developer carrying member disposed downstream of the first developer carrying member with respect to the direction of movement of the image bearing member, and designed such that one and the same electrostatic image on the image bearing member is developed with the developer carried on these developer carrying members, has a developer consumption mode in which during the other time than ordinary image formation, the developer borne on the first and second developer carrying members is shifted to the image bearing member, and during this developer consumption mode, control is effected so that the amount of developer consumed from the second developer carrying member to the image bearing member may be greater than the amount of developer consumed from the first developer carrying member to the image bearing member.
